Question about 1990 Oldsmobile Cutlass Calais
Just changed ignition switch and tumbler for unrelated reasons.
Car will not start. Symptoms are no spark/no injector pulse. Computer has no codes. Fuel pump cycles fine and there is good fuel pressure at the rail. When using diagnostic scanner, there is no RPM while turning car over....also shows 0 spark advance. Want to get thoughts before I start by throwing a crank sensor into it.
It would be the crank angle sensor which tells the computer if the engine is turning and at what speed and when to spark

Car not starting or turning over indicates towards multiple possibilities.
It can be issue with battery or weak battery. But if battery checks out ok, then
it can be starter issue or faulty alternator or problem with low fuel pressure
or no spark at spark plugs due to dirty spark plugs or faulty
ignition coil or injectors getting cracked or dirty and needs to be cleaned.
To confirm the problem, the basic troubleshooting is required.
